“Prove it.”
Petar smiled his grin again, only bigger and more self-assured. It was the attitude she had seen in his eyes when he’d disarmed her earlier in the night’s drama. It was the arrogance that had made her consider killing him then. For a moment, as she knew she might from that day on, she wondered if she should have.
They both knew that this interrogation was not perfunctory. As a homicide detective, Heat recognized that any case required solid proof for the DA. Which was why she had just assigned detectives to search Petar’s apartment as well as his office at the TV show he worked for. In addition, they’d run his entire life through a sifter for any evidence they could find. And that was just the start.
But Petar was trying to seed her with doubt. Nobody else had heard him admit to the murders any more than anyone else would know if she had shoved him in front of that train. If she couldn’t find physical proof that would stand up in court, Petar Matic would walk. Keenly aware of those stakes, he played his ace card. “I have something you want, you know.”
If she blinked and showed interest she would lose ground, and that could be the beginning of the unraveling of this case. So Heat remained stoic. She betrayed no tells and said nothing.
“And maybe it’s not just information about your mother’s killing. Or the other one.” He tossed it off as if these murders were just inventory items to be noted then dismissed from reflection. “Something is coming. It’s big and it’s bad. This has been in the works for ten years—if that period creates a context in any way for you.” His allusion to the decade that bookended the two stabbings was his way of teasing her interest without admitting guilt. Petar was smart. Nikki had to be smarter.
Without taking the negotiation bait, she said, “If you know Something about a pending crime, you are obligated to share that information.”
“Sound advice, Detective. Maybe I will.” He flashed her his arrogant grin again and said, “I guess that depends on the right arrangement.”
Irons was in the Ob Room with Rook when she came through the air lock from Interrogation. The captain rushed over to Nikki. “You’re not really going to bargain with this creep, are you?”
Heat glanced up at the wall clock. “What are you doing here after midnight, Captain?”
“I heard you nabbed our man and I wanted to be here.” She noticed he was freshly shaved and dressed in his duty uniform, with extra starch in the white shirt. Wally had taken time to get himself camera-ready. “You’ve got him to rights, don’t you?”
“Not that simple. He told me he murdered both victims, but it’s my word against his, unless we button him down hard. Even beyond that, there are things we need to know that his cooperation will bring to light.”
Irons scoffed. “Sure. And long as you’re letting him call the tune, why don’t you just spring him?” And when he remembered who else was in the room, he said to Rook, “Don’t print that.”
“Never heard it, Captain.”
“Petar is not going to spring anywhere, sir. I just think the prudent course is to take a breath, bide our time, and confer with the DA first thing in the morning.”
Irons said, “You just want to drag this out so you can satisfy your own personal curiosity about every little detail and loose end about your mother.”
Heat said, “Listen to me, Captain, nobody wants to see this guy sent away forever more than I. But that means getting it right so he doesn’t walk because someone got hasty and sloppy. We have him. Our job now is to make it stick.” Irons started to interrupt, but she plowed right over him. “And what if he’s not posturing? What if he does know something that will help us arrest conspirators and prevent someone else from getting killed? Do you call that just a loose end?”
